• Hill grew up in the same small California town as Shane Costa of the Royals organization. They are still friends.
  
  "I talk to him all the time; he's my best friend," Aaron said before 2005 spring training. "We grew up taping up balls and throwing them as batting practice at each other."
  
  Aaron said he went to a lot of Visalia Oaks (CAL) baseball games while growing up. "All the time. I used to be one of those kids trying to get the players' autographs. That's why I try and sign as many as I can every night as a player," Hill said. (David E Fanucchi-At The Yard Magazine-December, 2004)

Hill and Adams were fitted with tuxedo jackets with their numbers stitched on the back and an SUV, decorated with balloons and streamers, was waiting outside the stadium with "Just Married" written on the back window. Then, before the third inning of the game against the Phillies, the plane returned with another message: "Congratulations, Aaron and Russ."

• Hill is an infielder who can hit. He displays a quiet approach at the plate, effectively staying back on offspeed stuff. He uses a straightaway stance. His swing is short, compact, and easy. He is short to the ball and hits to any part of the park.
  
  Aaron's approach at the plate is similar to the one used by Hall of Famer Paul Molitor. When hitting, Hill drives his bat from a near-standstill position towards the ball. He doesn't move his hands back much before beginning his swing.

"Very few guys can do that and get away with it," Toronto manager John Gibbons said. "Molitor was an exception."

• Aaron has a beautiful compact swing. He hits line drives for a high average, a lot of doubles, and a few home runs. His power should improve every year as he learns to use his lower body for better leverage.
  
  Eventually, Hill should hit .280–.290 with 15–20 home runs per season.

• Aaron exhibits sure hands and good agility at shortstop. He has plenty of arm for making throws from deep in the hole. But he may not have the quickness, double-play pivot, and range to play shortstop every day --especially on artificial turf.
• Hill reads the ball off the bat well and positions himself to take away hits from the opposition.

• Hill is probably better at second base. And he should hit enough to play at third. Hill has the instincts and intelligenct to learn to position himself well enough to make up for his lack of quickness.

• In May 2006, Aaron moved from second base back to shortstop. Hill had become the full-time second baseman after Orlando Hudson was traded to Arizona in the offseason before 2006. But Russ Adams started slowly and was sent back to Triple-A, so Hill replaced him at short.

• Aaron has good speed and instincts on the bases.

• May 28, 2008: Aaron suffered a concussion after colliding with teammate David Eckstein during a game. He went on the D.L. over a week later, retroactive to May 30.
  
  Hill and Eckstein both ran sideways on a high popup in shallow by Rob Bowen that fell for a single and Eckstein's arm appeared to hit Hill in the head. Aaron was down and held his head for several minutes as Toronto's training staff examined his head and teeth before he walked off the field on his own.
  
  After being checked out at the University of Pittsburgh near the end of June, they recommended a two-week period of non-activity. But he ended up missing the rest of the season.
• Aaron received supprt from former Jays third baseman Corey Koskie and ex-Cardinal catcher Mike Matheny, both of whom had their careers cut short by concussions. They offered the key piece of advice in the recovery process: Don't push yourself to come back too soon.
  
  To aid in Hill's return, doctors tried various procedures, including acupuncture and jaw therapy, because the jaw is the primary balance point in the body.
